IMPROVEMENT IN 'VAPOR-BURNERS.

1 The Schedule referred to in these Letters Patent and making part of the same.

`To all twha/m it may concern:

Be it known that I, LOUIS FISCHER, of the city of Brooklyn, in the county of Kings, and State of New York, have made' certain new and useful Improvements in Vapor-Burners; and I do hereby declare tube and burner of the same.

Figure 3 is a longitudinal section of the wick-tube,

insulator, and snpply-pipe of the same, shown on .an

enlarged scale. v

Similar letters of reference indicate corresponding parts in the several figures.

The nature of this invention consists in providing a wire-screen, or perforated guards, to be employed on the air-passages ofthe burner-tube, so as to divide the current of air when coming in contact with the vapor, whereby the usual noise made in .using the burner is most effectually stopped, and the vapors are protected against condensation by cold or strong cur- -rents of air, and also against vibration, and the disturbance of their properly mixing and passing to the burner.

To enable others skilled in the art to make and use my improvements, I will'procced to describe their con- A represents the ordinary supply-tube leading to v the oil, from the basin to the wick.

B is the insulator, combining the wick-tube with the supply-pipe; and

C, the retort in which the gas is generated. p

D is the burner-tube, provided with the air-passages E E, and furnished with the usual valve F, and valve-passages G.

I provide the top end of the burner-tube with a round burner-tip, H, as shown, having passages 7a, hl through its cross-piece ,'leading from the main passage I of the burner-tube.

Now, in order to stop the usual noise in operating these burners, I employ a perforated guard, or wire Screen, K, over the air-passages E, which may be scoured in any convenient manner, and instead of wire, the screen, or guards may be constructed of other pertforated or porous substances, in any suitable manner, so as to divide the current of air passing through the said passages.

i In the ordinary vapor-burner, the wick-tube forms part of the supply-pipe, the'endof which is directly connected with the rear part l.of 'the retort, and when a new one is to be placed in it, theold one is removed by detaching the retort from said pipe, at their junction.

In using the burner, after a short .time the wick becomes burned, and in that case the end of the retort becomes frequently immovable, so that it is very difficult to remove the wick and replace it by another without destroying the supply-pipe by the Operation.

Now, in order to facilitate the removing ofthe said wick, I arrange the" supply-pipe with a junction, at a distance of several inches from its junction with the retort, and use that part for replacing the wick. I make this junction with a uilion-coupling,lprovided so as to insulate the heat from the retort and wick-tube from the supply-pipe, which consists in constructing .the end of the supply-pipe with the shoulder L, having a screw-thread on its periphery, over which is fitted a coupling-nut, M; and iu constructing the .corresponding end of the wick-tube with the shoulder N loosely iitting the inside diameter of the nutM, and having one, two, or more washers, O O, of pasteboard Or other insulating-material employed between the faces of the joining ends of the said pipes, while having a similar washer, P, employed on the rear face of the shoulder N; and between it and the inside shoulder Q of the nut M, I employ a metal washer, to protect the washer W from being torn or otherwise damaged in tightening the nut M.

'By these means, the supply-pipe is insulated from the wick-tube Very ciiectively, so that very little heat is conducted to it, and that a proper, easily-operating, and detachable connection is obtained between the supply and wick-tube, so that the wick of the burner may be withdrawn and replaced with more facility l than with those heretofore in use.

I am aware that a gate has been employed to regulate the quantity of air passing through the air-passages, as seen in Letters latent granted to D. H. Carpenter, August 4, 1857, whose invention I hereby disclaim; but A What I do claim my invention, and desire to secure by Letters Patent, is-

rlhe screen, or perforated guard K, in combination with the air-passages F F, when employed on vaporburners, substantially as and for the purpose herein set forth.
